MP6KE11CAE3 Equivalent & Substitute Parts

Part Overview

The MP6KE11CAE3 is a transient voltage suppressor (TVS) diode manufactured by Microchip Technology, designed for general-purpose overvoltage protection applications. This bidirectional Zener-type TVS diode operates with a reverse standoff voltage of 9.4V and provides clamping at 15.6V maximum, with a peak pulse current rating of 38A. The device is housed in a T-18 axial through-hole package and is qualified to MIL-PRF-19500 military standards. The part is currently active in production with 795 units in stock. Equivalent substitute parts are identified based on matching electrical performance parameters and compatible packaging configurations to support component procurement flexibility and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MP6KE11CAE3 are identified based on electrical parameter equivalence within the P6KE11 base product family. The substitution criteria are strictly defined by the following matched parameters:

• Voltage - Reverse Standoff (Typ): 9.4V
• Voltage - Breakdown (Min): 10.5V
• Voltage - Clamping (Max) @ Ipp: 15.6V
• Current - Peak Pulse (10/1000µs): 38A
• Power - Peak Pulse: 600W
• Bidirectional Channels: 1
• Type: Zener
• Mounting Type: Through Hole
• Moisture Sensitivity Level: 1 (Unlimited)

The P6KE11CA variant from Taiwan Semiconductor Corporation meets all electrical performance requirements and operates within the same functional parameters. The primary difference between the main part and substitute is the package configuration (T-18 versus DO-15) and packaging format (Bulk versus Tape & Reel), along with manufacturer and compliance certifications. Both devices are rated for general-purpose transient voltage suppression applications and share identical electrical specifications.

Parameter Comparison

Engineering Selection Recommendations

The P6KE11CA from Taiwan Semiconductor Corporation is electrically equivalent to the MP6KE11CAE3 and provides full functional substitution for general-purpose transient voltage suppression applications. Both devices deliver identical electrical performance across all critical parameters: reverse standoff voltage, breakdown voltage, clamping voltage, peak pulse current, and peak pulse power.

Selection between these parts should be based on the following considerations:

MP6KE11CAE3 (Microchip Technology): Maintains military-grade qualification per MIL-PRF-19500 and is supplied in bulk packaging. This configuration is appropriate for applications requiring military-grade certification or where bulk packaging aligns with procurement workflows. The device is RoHS non-compliant.

P6KE11CA (Taiwan Semiconductor Corporation): Provides ROHS3 compliance and is supplied in Tape & Reel format, supporting automated assembly processes and modern supply chain requirements. This configuration is appropriate for high-volume production environments and applications with RoHS compliance mandates. Operating temperature range is not specified in available documentation.

Both parts are active products with adequate inventory availability. Package differences (T-18 versus DO-15) require verification of board layout compatibility, as these are distinct axial through-hole package geometries. The choice between these substitutes depends on compliance requirements, packaging format needs, and specific application constraints.

Frequently Asked Questions (FAQ)

Q: Are the MP6KE11CAE3 and P6KE11CA electrically interchangeable?

A: Yes. Both devices share identical electrical specifications: 9.4V reverse standoff voltage, 10.5V minimum breakdown voltage, 15.6V maximum clamping voltage, 38A peak pulse current, and 600W peak pulse power. They are functionally equivalent for transient voltage suppression applications.

Q: What is the primary difference between these two parts?

A: The main differences are package configuration (T-18 versus DO-15), packaging format (Bulk versus Tape & Reel), manufacturer (Microchip versus Taiwan Semiconductor), and compliance certifications (Military MIL-PRF-19500 versus ROHS3). Electrical performance is identical.

Q: Can I use the P6KE11CA as a direct replacement for the MP6KE11CAE3 on an existing PCB?

A: Package compatibility must be verified. While both are axial through-hole devices, the T-18 and DO-15 packages have different physical dimensions and lead spacing. PCB layout and hole positioning must accommodate the substitute package geometry.

Q: Does the P6KE11CA meet military specifications?

A: The P6KE11CA is not specified as military-grade. The MP6KE11CAE3 carries MIL-PRF-19500 qualification. If military-grade certification is a requirement, the MP6KE11CAE3 must be used.

Q: Is the P6KE11CA RoHS compliant?

A: Yes. The P6KE11CA is ROHS3 compliant. The MP6KE11CAE3 is RoHS non-compliant. If RoHS compliance is required, the P6KE11CA is the appropriate selection.

Q: What is the operating temperature range for the P6KE11CA?

A: The operating temperature range for the P6KE11CA is not specified in the provided documentation. The MP6KE11CAE3 operates from -65°C to 150°C (TJ). Verify the P6KE11CA operating temperature range with the manufacturer if this parameter is critical for your application.

Q: Are both parts currently in stock?

A: Yes. The MP6KE11CAE3 has 795 units in stock. The P6KE11CA has 8020 units in stock. Both are active products with available inventory.

Q: What does the base product number P6KE11 indicate?

A: The P6KE11 is the base product designation for this TVS diode family. Both the MP6KE11CAE3 and P6KE11CA are variants within this product line, differentiated by manufacturer, package type, and compliance certifications while maintaining identical electrical specifications.
